LAMP HEATERATTACHMENT.

SPECIFICATION forming part Of Letters Patent No. 524,667, dated August14, 1894.

Application filed December 22, 1893. Serial No. 494,420- (No modeli) ToaZZ whomit may concern.-

Be it known that I, ALEXANDER H. OoWEN,

a citizen of the United States, residing in the clare the following tobe a full, clear, and exact description of the same.

My invention relates to a heating attachment for lamps, and it consistsin certain details of construction which will be more fully explained byreference to the accompanying drawings, in which- Figure 1 is a sideelevation of a lamp showing a sectional view of the heating device. Fig.2 is a perspective view of the support for the heater.

The object of my invention is to provide an attachment for the ordinaryilluminating lamp, whereby the heat from thelamp chimney is received andradiated so as to warm the air of the room.

A is a lamp of any suitable or convenient form, having the ordinarychimneyB such as is used for illuminating purposes.

C is a ring of a little larger diameter than that of the top of thechimney.

D D are vertically arranged hooks fixed to the ring and turned overtoward the inside so that the bight or upper curves of the hooks willrest upon the top of the chimney, thus supporting the ring in ahorizontal position. The wire of which this hook is formed extendsoutwardly and radially beyond the ring 0, as shown at E, and at theouter ends these wires are bent so as to clasp a supplemental ring F oflarger diameter than the ring C and which is concentric therewith. Theouter ends of the wires E after clasping the outer ring to which theyare secured, extend upwardly as shown at E, and thus form guides withinwhich the lower edge of the heating drum G is received. This drum isthus supported above the lamp chimney, so that all theheated air andproducts of combustion from the lamp enter the drum, passing up to thetop, thence being deflected downwardly between the outer and innercylinders of which the drum is formed, the inner cylinder being shorterthan the outer one, and leav ing a passage H between the upper edge and-the top for this purpose, thus heating the drum as well as escapingthrough the openings I around the bottom as shown. The heat thusradiated from the drum is sufficient to raise the temperature in anyroom of ordinary size so as to make it comfortable in any but extremecold weather.

By supporting the heater directly upon the top of the chimney, noseparate supplemental stand is required and the apparatus is more cheapand convenient.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The heater attachment for lamp chimneys consisting in two concentricrings, C, F, and a series of horizontal connecting wires E, formed withbends holding and clasping said rings in proper relation to each other;the outer ends of said wires being bent upwardly into arms E to receivethe lower end of a drum, and the inner ends of said wires terminating inthe vertically extending downwardly opening hooks D adapted to receivethe upper end of a lamp chimney within them and rest upon its upper edgeand a drum G mounted within the said arms E, substantially as hereindescribed.

Indwitness whereof I have hereunto set my han ALEXANDER H. COWEN.
